INTRODUCTORY 

Dampness  is  a  destructive  force  existing  in  every  locality,  from 
w^hich  no  materials  are  exempt. 

Every  class  of  building  construction  requires  waterproofing 
protection  in  some  form. 

This  catalog  comprehensively  explains  the  use  and  applica¬ 
tion  of  Crescent  Protective  Products.  It  gives  specific  informa¬ 
tion  regarding  the  various  methods  of  integral  waterproofing,  sur¬ 
face  waterproofing  and  damp-proofing,  and  the  treatment  of  con¬ 
crete  floors  to  procure  wear-resisting  surfaces.

CRESCENT  WATERPROOFING 


Paste  and  Powder 


The  simplest  and  most  effective  method 
of  waterproofing  cement  mixtures  is  the 
incorporation  of  the  waterproofing  agent  as 
an  integral  part  of  same.  This  applies  to 
concrete,  cement  mortar  coatings  and  ce¬ 
ment  stucco. 

Combating  water  pressure  is  a  matter 
for  serious  consideration,  for  it  must  be  re¬ 
membered  that  an  upward  pressure  of  one 
foot  of  water  means  an  upward  lift  of  62|/2 
pounds  per  square  foot. 

Crescent  Waterproofing  combines  the 
protective  elements  necessary  to  produce 
cement  work  which  will  be  permanently 
water  repellent. 

The  principle  by  which  Crescent  Water¬ 
proofing  performs  its  function  differs  from 
other  integral  waterproofing  compounds. 

Crescent  Waterproofing  depends  upon  a 
combination  of  its  constituents  with  lime  in 


the  cement  mixture  in  order  to  develop  its 
water-repellent  properties.  In  practically 
every  other  waterproofing  compound,  the 
combination  with  lime  is  made  prior  to  its 
introduction  into  the  cement  mixture. 

The  active  waterproofing  elements  embodied 
in  Crescent  Waterproofing  are  introduced  in 
solution  in  the  water  used  for  tempering  con¬ 
crete,  cement  mortar  or  cement  stucco. 

The  tempering  water,  therefore,  distributes 
the  waterproofing  throughout  the  cement  mix¬ 
ture,  making  the  entire  mass  water-repellent. 
This  distribution  is  complete,  for  cement  will  not 
hydrate  without  combining  with  water,  and  each 
water  molecule  carries  its  proportion  of  active 
waterproofing. 

Crescent  Waterproofing  is  made  in  both 
paste  and  powder  form.  The  method  of  using 
each  is  described  in  the  specifications  in  the  lat¬ 
ter  half  of  this  book.  The  use  of  either  paste  or 
powder  is  optional,  depending  on  individual 
preference.

Ceresit  Waterproofing  Compound 


The  Ceresit  formula  was  conceived  and 
developed  by  a  German  Chemist.  The 
American  manufacturing  rights  were  owned 
by  the  Ceresit  Waterproofing  Co.  until 
1922,  when  that  company  was  absorbed  by 
the  Crescent  Sales  &  Mfg.  Co. 

The  test  of  time  is  the  trade  mark  of 
quality.  Ceresit  was  one  of  the  first  integral 
waterproofing  compounds  on  the  market, 
and  for  nearly  twenty  years  has  been  used 
successfully  in  thousands  of  representative 
installations. 

Ceresit  Waterproofing  Compound  is  a 
plastic  paste  of  the  consistency  and  appear¬ 
ance  of  ice  cream.  It  is  mixed  with  the 
gauging  water  used  for  tempering  concrete, 
cement  mortar  or  cement  stucco,  mixing 
first  one  part  of  water  and  Ceresit,  then 
adding  additional  water  as  shown  in  the 
Ceresit  specifications  on  page  1 4.  This 
makes  a  milky  solution  which  is  used  in¬ 
stead  of  plain  water  for  mixing  the  cement 
and  aggregates. 

The  success  of  Ceresit  is  due  solely  to 
its  ability  to  seal  the  capillary  pores  in  con¬ 
crete  and  other  cement  mixtures  surely  and 
permanently.  Its  continued  use  covering 
a  period  of  years  by  leading  architects  and 
engineers,  as  well  as  many  industrial  corpo¬ 


rations  and  railroads,  is  the  best  evidence 
possible  of  its  ability  to  give  uniform  and 
continued  service. 


Wherever  water  is  to  be  kept  in  or  out, 
Ceresit  can  be  used  with  the  confidential 
expectation  that  it  will  do  the  work  for 
which  it  is  intended.

Crescent  Plaster  Bond 

It  is  often  desired  to  apply  plaster  di¬ 
rectly  on  the  inside  of  brick  walls  where 
they  are  the  outer  walls  of  the  building. 

Crescent  Plaster  Bond  provides  a  bond 
for  the  plaster,  and  eliminates  the  use  of 
lathing  or  furring.  It  also  prevents  moisture 
penetration,  which  discolors  and  ruins  the 
plaster.  In  addition,  it  insulates  the  walls, 
retarding  the  passage  of  heat  and  cold. 

One  or  two  coats  can  be  applied,  but  a 
heavy  application  must  be  secured,  as  too 
thin  a  coat  is  insufficient  for  bonding  the 
plaster. 

Plastering  can  be  done  24  hours  after 
the  Plaster  Bond  is  applied;  it  is  advisable 
to  do  the  work  within  ten  days  to  avoid  the 
possibility  of  the  Plaster  Bond  becoming 
dust  coated. 

We  do  not  recommend  the  use  of  ce¬ 
ment  mortar  over  Crescent  Plaster  Bond, 
and  when  used,  only  one  coat  can  safely  be 
applied. 

Crescent 

Metallic  Hardener 

Crescent  Metallic  Hardener  is  a  ground 
compound,  which  is  incorporated  in  the  top 
dressing  of  concrete  floors. 

The  jagged,  irregularly  shaped  particles 
interlock  with  the  setting  of  the  cement  top¬ 
ping,  which,  with  the  corrosion  of  the  metal, 
gives  a  surface  of  intense  hardness  and  re¬ 
markable  wear  resisting  properties. 

Crescent  Metallic  Hardener  is  made  in 
two  colors.  The  plain  hardener  gives  a 
steel  gray  finish  and  is  for  use  in  mills,  fac¬ 
tories,  loading  platforms  and  all  types  of 
industrial  work. 

Crescent  Red  Hardener  is  adapted  for 
theatres,  schools,  porches,  sun  parlors,  ter¬ 
races,  etc.,  wherever  service  and  attractive¬ 
ness  are  to  be  combined. 


Crescent  Damp-proofing 

Even  where  foundations  are  not  sub¬ 
jected  to  water  pressure,  they  should  be 
protected  against  moisture,  because  surface 
water  percolates  through  the  soil  and  into 
or  through  the  foundation. 

Crescent  Damp-proofing  applied  on  the 
outside  of  foundation  walls  gives  this  pro¬ 
tection.  Its  use,  however,  is  not  confined 
to  foundation  work.  Wherever  dirt  is  to  be 
filled  in  against  walls.  Crescent  Damp-proof¬ 
ing  should  be  applied,  unless  waterproofing 
is  used  in  the  concrete  itself. 

Wood  floors  laid  over  a  concrete  base 
can  be  protected  from  rotting  by  applying 
Crescent  Damp-proofing  to  the  concrete  be¬ 
fore  laying  the  floors. 

Crescent  Damp-proofing  has  a  high 
grade  asphaltic  base,  combined  with  pre¬ 
servative  elements  to  protect  the  paint  from 
disintegration  and  peeling. 

It  is  also  used  in  a  modified  form  for 
stainproofing  building  stone. 

Indurite 

Liquid  Hardener 

Indurite  Liquid  Concrete  Hardener  is  a 
colorless  chemical  compound,  which,  when 
applied  to  Portland  cement  surfaces,  changes 
them  into  a  flinty,  granite-like  hardness, 
making  them  at  the  same  time  impervious 
to  the  action  of  oils  and  moisture. 

The  effect  of  Indurite  is  that  of  chem¬ 
ically  transforming  the  cemented  surface, 
making  it  harder,  and  binding  the  granular 
surface  into  greater  compactness. 

Indurite  prevents  the  dusting  of  cement 
floors  by  making  them  abrasion  resistant. 
Its  use  in  every  type  of  industrial  plant  is 
economy  from  the  standpoint  of  equipment 
efficiency  alone.

Cem-Bric 

Covering  Compound 

The  distinguishing  quality  of  this  brick 
and  cement  coating  is  its  perfect  affinity  for 
cement,  brick,  stucco  and  other  plastered 
surfaces.  It  seals  the  surface  pores,  provid¬ 
ing  a  perfect  vs^aterproof  film  of  lasting 
quality. 

Cem-Bric  protects  and  beautifies,  mak¬ 
ing  it  a  most  desirable  paint  for  every  class 
of  ornamental  concrete  and  cement  work 
and  buildings  of  brick,  stucco,  concrete 
block  and  stone.  For  painting  cement 
floors,  its  hard  film  makes  it  an  extremely 
durable  floor  finish. 

For  interior  plastered  surfaces,  Cem- 
Bric  gives  a  soft,  velvety  flat  finish  which 
is  washable. 

Cem-Bric  is  made  in  seven  regular 
colors  and  can  be  furnished  in  any  shade 
desired. 


Cresolac 

Transparent  Waterproofing 

Mineral  building  materials  are  porous 
to  a  greater  or  less  degree.  Many  kinds  of 
brick,  limestone  and  many  other  materials 
absorb  moisture.  Stucco  and  cement 
blocks,  if  not  waterproofed  integrally,  ab¬ 
sorb  dampness. 

Cresolac,  painted  on  such  porous  sur¬ 
faces,  prevents  moisture  absorption.  It 
leaves  no  film,  does  not  affect  the  color  of 
the  treated  surface,  but  penetrates  and 
closes  the  pores,  thus  preventing  capillary 
attraction. 

Cresolac  has  many  uses,  such  as  water¬ 
proofing  stucco  and  brick  buildings,  monu¬ 
ments  of  soft  stone,  cement  blocks,  outside 
concrete  work,  etc.  It  makes  an  ideal  base 
for  oil  paint,  but  cannot  be  applied  over  oil 
paint.

INTEGRAL  METHOD 

General.  Describing  the  integral  method  of  waterproofing  res¬ 
ervoirs,  cisterns,  pits,  basements,  swimming  pools,  burial  vaults  and 
other  below  grade  concrete  work. 

Material.  The  waterproofing  material  shall  be  Crescent  Water¬ 
proofing  (paste  or  powder  as  preferred)  as  manufactured  by  Crescent 
Sales  &  Manufacturing  Co,,  Chicago,  and  used  in  accordance  with 
these  specifications. 

Proportions.  The  concrete  shall  be  1  -2-4  mix,  using  clean  sand, 
and  stone  uniformly  graded  from  Yi"  to  1  Yi' . 

Waterproofing.  The  use  of  paste  or  powder  is  optional,  depending  on  individ- 
preference,  the  waterproofing  results  being  equally  efficient. 


CRESCENT  PASTE 

Temper  the  concrete  aggregates  with 
following  solution:  Mix  1  part  each  of  Cres¬ 
cent  Waterproofing  Paste  and  water,  then 
add  23-35  parts  water  (depending  on  se¬ 
verity  of  waterproofing  conditions),  propor¬ 
tions  in  final  solution  to  be  1  part  Crescent 
Waterproofing  Paste,  24-36  parts  water. 

Or,  add  Crescent  Waterproofing  Paste 
to  concrete  aggregates  in  the  mixer,  figuring  on 
the  basis  of  8-12  lbs.  of  Crescent  Waterproof¬ 
ing  Paste  to  cubic  yard  of  concrete. 


CRESCENT  POWDER 

Use  2  lbs.  of  Crescent  Waterproofing 
Powder  to  each  bag  of  cement,  that  is,  add 
2%  of  Crescent  Waterproofing  Powder  to  the 
cement  by  weight.  Mix  the  dry  cement  and 
waterproofing  powder  thoroughly,  then  add 
the  sand.  Add  water  and  stone  and  mix  in 
customary  way. 

Or,  add  Crescent  Waterproofing  Powder 
to  the  aggregates  in  the  mixer  on  the  basis  of 
2  lbs.  of  Crescent  Waterproofing  Powder  to 
each  bag  of  cement,  that  is,  2%  of  the  amount 
of  cement  by  weight. 


Placing.  For  uniform  density  concrete  must  be  spaded  well  and  puddled  to 
quaking  consistency,  pouring  in  continuous  operation  if  possible.  Otherwise,  roughen 
old  surface  and  flush  with  water  and  apply  slush  coat  of  waterproofed  cement,  pro¬ 
ceeding  with  concrete  pouring  while  surface  is  still  wet. 

Drainage  System.  For  successful  waterproofing  results  water  pressure  must  be 
removed  until  concrete  is  set,  using  pump  or  other  means  of  relieving  pressure.

cement  mortar  for  each  J/4"  thickness. 


Mix  the  dry  cement  and  Crescent  Water¬ 
proofing  Powder  thoroughly,  add  the  sand, 
then  add  the  water,  mixing  and  turning  over 
constantly  until  a  thoroughly  plastic  mortar  is 
secured.  Use  2  lbs.  of  Crescent  Powder  to 
each  bag  of  cement,  that  is,  add  2  %  of  Cres¬ 
cent  Powder  to  the  amount  of  cement  by 
weight. 


Relieving  Water  Pressure.  Dig  sump  below  floor  surface  and 
pump  or  bail  water  out  as  necessary.  All  pressure  must  be  relieved 
until  cement  mortar  is  fully  set. 

Initial  Surface  Treatment.  Rake  joints  in  brick  or  rubble  walls, 
wire  brush  and  wash.  Apply  waterproofed  neat  cement  wash  of 
creamy  consistency,  keeping  just  ahead  of  application  of  scratch  coat. 
On  concrete  walls,  roughen  surface,  wire  brush  and  wash.  Flush 
with  water  to  full  capacity  and  apply  waterproofed  neat  cement  wash, 
keeping  just  ahead  of  scratch  coat. 


Application.  Following  above  operation,  apply  waterproof  cement  plaster  coat 
to  walls  to  thickness  of  working  thoroughly  into  place.  Scratch  when  sufficiently 
set.  Treat  with  a  waterproofed  neat  cement  wash  and  while  still  damp  apply  finish 
coat.  After  initial  set,  float  or  trowel  to  smooth,  hard  finish.  Apply  a  one-inch 
waterproofed  cement  topping  on  floor  in  one  continuous  layer.  Cove  out  juncture  of 
floor  and  walls  so  as  to  secure  perfect  joint. 


Outside  Walls 

Follow  above  specifications  and  in  addition  proceed  as  follows: 

Footings.  Apply  waterproofed  plaster  coat  1  Yi"  thick  over  top 
of  footings  and  1  foot  down  each  side.  If  footings  are  already  set, 
roughen  surface  and  wash  with  waterproofed  neat  cement,  then 
apply  plaster  coat. 

Walls.  After  side  wall  is  placed,  apply  waterproofed  plaster 
coat  thick,  working  thoroughly  into  place.  Scratch  when  suffi¬ 
ciently  set,  treat  with  waterproofed  neat  cement  wash,  and  while  still 
damp  apply  finish  coat.  After  initial  set,  float  or  trowel  to  smooth, 
hard  finish.

Waterproofing  Cement  Stucco 


General.  The  penetration  of  moisture  in  stuccoed  surfaces  causes  hair  cracking 
and  disintegration  on  account  of  extremes  in  temperature;  also  unsightly  discolora¬ 
tion.  Waterproofed  stucco  is  lasting  because  the  surface  repels  moisture  and  there¬ 
fore  every  rain  washes  and  cleans  the  stucco.  On  the  other  hand,  if  not  waterproofed, 
the  rain  drives  the  dust  and  dirt  which  collects  on  the  surface  into  the  stucco,  with 
the  result  that  the  expansion  due  to  alternate  freezing  and  thawing  permanently  in¬ 
jures  the  stucco  coating.  The  use  of  waterproofing,  therefore,  provides  an  economical 
and  efficient  method  of  procuring  impermeable  stucco  which  will  be  permanent. 

Portland  cement  stucco  has  given  the  best  service  of  any  material  in  use  for 
this  class  of  work.  Experiments  are  always  costly  and  it  is  therefore  wise  to  be  sure 
when  deciding  a  matter  of  such  importance  as  this,  to  select  the  kind  of  stucco  which 
will  be  lasting. 

Proportions.  For  three-coat  work,  the  first  two  coats  shall  be  1  part  Portland 
Cement  and  2  parts  clean  sand.  The  third  coat  shall  be  1  part  Portland  Cement  and 
2Y2  parts  sand. 

Waterproofing.  The  waterproofing  material  shall  be  Crescent  Waterproofing 
(paste  or  powder  as  preferred)  as  manufactured  by  Crescent  Sales  &  Manufacturing 
Co.,  Chicago,  and  used  as  per  instructions  below: 


CRESCENT  PASTE 


CRESCENT  POWDER 


Dry  mix  cement  and  sand  and  temper 
with  following  solution:  Thoroughly  mix  1 
part  each  Crescent  Paste  and  water,  then  add 
11-15  parts  water,  proportions  in  final  solution 
to  be  1  part  Crescent  Paste,  12-16  parts  water. 

Amount  required,  3  lbs.  per  1 00  sq.  ft. 
for  each  Y4"  thickness. 


Mix  the  dry  cement  and  Crescent  Water¬ 
proofing  Powder  thoroughly,  add  the  sand, 
then  add  the  water,  mixing  and  turning  over 
constantly  until  a  thoroughly  plastic  mortar  is 
secured.  Use  from  2  to  3  lbs.  Crescent  Water¬ 
proofing  Powder  to  each  bag  of  cement,  that 
is,  2%  to  3%  of  Crescent  Powder  to  the 
amount  of  cement  by  weight. 


Application.  The  first  stucco  coat  shall  be  Y%"  thick.  In  mixing  same  add  1 
shovel  of  heavy  fibred  mortar  for  every  bag  of  cement  when  stucco  is  applied  over 
metal  lath,  wire  cloth  or  wood.  This  coat  shall  be  scratched  diagonally  and  allowed 
to  set.  While  still  damp  apply  second  coat  YY'  thick,  which  shall  also  be  scratched. 
Apply  both  coats  continuously  in  one  general  direction.  Make  necessary  joints  at 
some  natural  division  of  the  surface  as  window  and  door.  The  third  or  final  coat 
shall  be  Ya"  thick. 

Finish.  Many  attractive  finishes  can  be  secured,  samples  and  specifications  of 
which  will  be  forwarded  on  request. 

Drying  Out.  Permit  the  last  coat  to  dry  out  slowly,  protecting  same  by 
sprinkling. 

Protecting  Outside  Concrete  Work 


General.  The  use  of  waterproofing  is  highly  desirable  in  outside  cement  work 
such  as  pergolas,  fountains,  concrete  bridges,  pylons,  culverts  and  similar  types  of 
work. 

Waterproofing.  The  use  of  paste  or  powder  is  optional,  depending  on  individ¬ 
ual  preference,  the  waterproofing  results  being  equally  efficient.  Follow  the  specifi¬ 
cations  for  waterproofing  mass  concrete.

Waterproofing  Cement  Stucco 

Moisture  penetration  in  stuccoed  surfaces  causes  discoloration  and  hair  cracking. 
Alternate  freezing  and  thawing  of  unwaterproofed  stucco  means  eventual  disintegra¬ 
tion.  Waterproofed  stucco  repels  moisture,  so  every  rain  washes  and  cleans  the  sur¬ 
face.  The  use  of  waterproofing,  therefore,  provides  an  economical  and  sure  method 
of  securing  permanent  stucco.  Use  Ceresit  in  the  same  manner  as  for  waterproofing

Crescent  Damp-proofing 

General.  These  specifications  cover  the  damp-proofing  of  foun¬ 
dation  walls  surrounding  excavated  portions  of  building. 

Material.  All  outer  foundation  walls  shall  be  damp-proofed  with 
Crescent  Damp-proofing  as  manufactured  by  Crescent  Sales  &  Manu¬ 
facturing  Co.,  Chicago,  and  used  according  to  directions  below: 


Preparing  Surface.  Rake  out  mortar  joint  on  brick  walls  to  form  key.  Thoroughly  flush 
with  water  and  apply  cement  plaster  coat  from  outer  edge  of  footing  to  grade  level.  Con¬ 
crete  walls  must  be  thoroughly  cleaned,  and  holes,  cracks,  etc.,  pointed  up. 


Application.  After  above  operation,  apply  Crescent  Damp-proofing  with  large  brush  from 
outer  edge  of  footing  to  2"  above  grade  level.  Retouch  portions  not  having  glossy,  black  ap¬ 
pearance.  After  first  coat  is  dry  apply  second  coat. 

Covering  Capacity.  Single  coat,  60-70  sq.  ft.  per  gallon  on  brick;  70-80  sq.  ft.  per  gallon 
on  concrete.  For  two  coats,  40-50  sq.  ft.  per  gallon. 


FUling  In.  Do  not  back  fill  with  earth  until  the  damp-proofing  has  had  sufficient  time  to 
become  thoroughly  dry. 

Covering  Capacity.  About  50  sq.  ft.  per  gallon  for  both  coats. 


Protecting  Wood  Floors  Laid  Over  Wood  Base 

General.  Where  wood  floors  are  laid  over  a  concrete  base  it  is  essential  that  a  protective, 
damp-proof  coating  be  applied  on  the  concrete  to  protect  the  wood  floors  from  rotting.  The 
use  of  Crescent  Damp-proofing  supplies  an  economical  method  of  insulation  to  protect  the  wood 
floors  from  the  effects  of  moisture  penetration. 

Application.  After  concrete  is  thoroughly  cleaned,  apply  heavy  saturating  coat  of  Cres¬ 
cent  Damp-proofing.  After  first  coat  is  dry  apply  second  coat. 

Sleepers.  After  damp-proofing  is  dry,  lay  wood  sleepers  and  fill  in  with  lean  mortar  in 
usual  way.  After  allowing  three  days  for  drying,  lay  wood  floor. 


Crescent  Plaster  Bond 

General.  This  material  provides  a  damp-proofing  and  bonding 
coat  for  the  inner  surfaces  of  outer  or  exposed  walls  over  which  plas¬ 
ter  is  to  be  applied.  It  is  not  recommended  for  ceiling  work. 

Material.  The  interior  surfaces  of  all  exposed  walls  shall  be 
coated  with  Crescent  Plaster  Bond,  as  manufactured  by  Crescent 
Sales  &  Manufacturing  Co.,  Chicago,  and  used  in  accordance  with

Indurite  Liquid  Hardener 

A  Liquid  Chemical  Compound  for  Wear-proofing  and  Dust-proofing 

Concrete  Floors 

General.  Indurite  is  a  colorless,  chemical  compound,  which,  when  applied  to  a 
cemented  surface,  forms  a  combination  of  intense  hardness  and  density,  the  process 
being  that  of  chemical  reaction. 

Length  of  service  is  the  attribute  required  of  a  concrete  floor.  New  floors  treated 
with  Indurite  Liquid  Hardener  are  made  more  efficient  because  they  will  give  longer 
service,  and  old  floors  can  be  reclaimed  for  added  years  of  usefulness  by  exactly  the 
same  method  as  in  treating  new  floors. 

The  use  of  Indurite  reduces  dusting  to  a  minimum,  which  protects  bearings  of 
machinery  and  shaft  hangers,  and  keeps  to  the  lowest  point  air  suspended  dust.  Its 
use,  therefore,  is  a  logical  means  of  reducing  the  cost  of  floor  maintenance. 

Directions  for  use:  Sweep  the  floor  and  remove  all  foreign  matter  such  as  oil 
and  grease.  Workmen  should  wear  rubbers  or  rubber  boots  as  Indurite  eats  leather. 

First  Coat :  Dilute  Indurite  with  water  half  and  half,  as  this  diluted  solution  in¬ 
sures  deeper  penetration.  Flush  the  material  over  the  floor  surface  generously,  scrub¬ 
bing  in  thoroughly  with  long-handled  brooms  having  stiff  bristles.  Go  over  the  floor 
repeatedly  until  soaked  to  full  absorbent  capacity. 

Second  Coat :  Do  not  dilute  second  application,  but  use  Indurite  full  strength, 
flushing  over  the  floor  and  using  same  degree  of  thoroughness  as  in  applying  the  first 
coat.  Allow  several  hours  between  coats.  If  a  white  precipitate  remains  on  the  sur¬ 
face,  wash  off  with  hot  water,  cleaning  up  with  a  rubber  squeegee  such  as  used  in 
washing  windows. 

Where  the  condition  of  the  floor  demands,  three  applications  may  be  advisable. 

Covering  Capacity:  For  both  coats,  approximately  100  sq.  ft.  per  gallon. 

Crescent  Metallic  Floor  Hardener 

General.  Crescent  Metallic  Hardener  is  a  ground  iron  compound  to  be  incor¬ 
porated  in  the  topping  of  concrete  floors  for  protection  against  dusting  and  to  render 
them  capable  of  resisting  heavy  service. 

The  use  of  Metallic  Floor  Hardener  is  not  intended  as  a  cure-all  because  poor 
workmanship  will  ruin  a  floor  where  Metallic  Hardener  is  used,  just  the  same  as  when 
cement  only  is  used.  Careful  workmanship,  therefore,  is  just  as  necessary  in  placing 
concrete  floors  of  Metallic  Hardener,  which  is  true,  of  course,  in  every  class  of  con¬ 
struction  work. 

This  method  of  concrete  floor  hardening  is  in  common  usage  and  has  become  a 
standard  specification.  The  jagged  particles  of  metal  interlock  when  the  cement  top¬ 
ping  sets,  and  this,  together  with  the  corrosion  of  the  metal,  gives  the  floor  surface 
intense  density. 

DUST  COAT  APPLICATION 

Apply  cement  topping  in  ordinary  manner.  When  partially  set,  float  to  even  and  true 
surface.  Dust  over  same  a  mixture  of  25  lbs.  each  of  Metallic  Hardener  and  Portland  Cement 
per  each  1  00  sq.  ft.  of  surface.  Float  in  and  trowel.  Give  surface  a  second  troweling  at  proper 
time  to  make  a  smooth,  even  finish.  Protect  floor  with  wet  sand  or  sawdust  for  several  days.

Cembric  Covering  Compound 

A  Decorative,  Waterproof  Coating  for  Brick,  Stucco  and  Similar 

Surfaces,  and  for  Concrete  Floors 

General.  Cem-bric  Covering  Compound  is  a  specially  prepared  paint  having  the 
property  of  entering  and  sealing  the  pores  of  the  surface  treated,  permanently  water¬ 
proofing  same. 

Cem-bric  is  adapted  for  exteriors  of  buildings  of  brick,  cement  and  similar  ma¬ 
terials  of  a  porous  nature.  It  not  only  waterproofs  but  provides  an  attractive  exterior, 
being  made  in  white,  cream,  buff,  cement  gray,  tile  green,  brown  and  brick  red. 

Cem-bric  differs  from  other  classes  of  paint  because  of  its  affinity  for  cement 
and  brick  surfaces  and  its  property  of  pore  penetration.  At  the  same  time  on  account 
of  its  peculiar  waterproofing  properties  it  successfully  prevents  the  entrance  of  mois¬ 
ture. 

Cem-bric  white  No.  1  0 1  makes  a  perfect  undercoat  for  application  on  plastered 
surfaces  to  be  enameled.  Cem-bric  in  any  color  makes  an  efficient  and  attractive  paint 
to  use  on  interior  plastered  walls  and  ceilings,  making  it  a  very  desirable  coating  for 
offices,  show  rooms,  etc. 

Specifications.  Exteriors.  TTie  surface  must  be  perfectly  dry  and  clean.  Apply  a  flowing 
coat  of  Cem-bric,  using  ordinary  paint  brush,  thoroughly  saturating  the  surface.  Thin  first  coat 
with  turpentine  if  necessary.  Allow  first  coat  to  dry,  then  apply  second  coat  without  thinning. 

Concrete  Floors.  Sweep  floor  surface  clean  and  remove  loose  particles  of  dirt,  grease  and 
oil.  Apply  a  flowing  coat,  thinning  if  necessary  with  turpentine.  After  first  coat  dries  apply 
second  coat  without  thinning. 

Covering  Capacity.  150-200  sq.  ft.  per  gallon  for  both  coats,  depending  largely  on  the 
porosity  of  the  surface. 

Cresolac  Transparent  Waterproofing 

A  Waterproofing  Liquid  for  Surface  Application  Which  Does  Not  Discolor  or 

Change  the  Treated  Surface 

Cresolac  is  a  protective  waterproofing  liquid  to  be  applied  over  exteriors  of 
stucco,  brick,  stone  or  similar  porous  material.  It  leaves  no  film,  but  enters  and  ef¬ 
fectively  seals  the  pores,  waterproofing  the  surface. 

Cresolac  does  not  change  the  color  of  the  treated  surface  and  its  use  provides 
permanent  protection  for  any  porous  structure. 

The  use  of  Cresolac  provides  a  simple  and  economical  method  of  waterproofing 
exteriors  where  protection  is  desired  without  changing  in  any  way  the  surface  color. 

Directions.  Apply  with  wide  brush  or  spray  in  two 'coats  several  hours  apart  over  dry 
and  dirt  free  surface. 

Covering  Capacity.  150-200  sq.  ft.  per  gallon  for  both  coats.

Hydrolac  Acidproofing 

A  special  acid  and  alkali  resistant  coating  for  every  class  of  work  where  a  pro¬ 
tective  paint  of  this  nature  is  required. 

The  highly  protective  value  of  this  material  is  evident  from  the  fact  that  in  a 
recent  acid  splash  test  made  by  one  of  the  chemical  manufacturers,  two  coats  of 
Hydrolac  Acidproofing  were  not  affected  by  either  sulphuric,  nitric  or  muriatic  acids. 

Directions.  Surface  must  be  dry  and  clean.  Apply  in  two  coats,  allowing  first  coat  to 
dry  thoroughly. 

Covering  Capacity.  350-400  sq.  ft.  per  gallon  each  coat. 

Hydrolac  Structural  Coating 

A  black,  protective  coating  with  elaterite  base,  which  will  stand  the  stress  of 
extreme  climatic  changes.  This  paint  is  adapted  for  structural  steel  work,  bridges, 
fire  escapes,  gas  tanks  and  general  structural  work. 

It  will  be  seen  from  the  above  that  Hydrolac  Structural  Coating  is  a  paint  for 
general  use.  It  is  made  in  black  only.  On  account  of  its  waterproofing  qualities  it 
is  adaptable  for  a  variety  of  purposes.  It  possesses  great  durability  and  is  highly 
resistant  to  the  action  of  moisture,  gases,  etc. 

Directions.  Apply  in  two  coats  to  clean  and  dry  surface,  allowing  first  coat  to  dry  thor¬ 
oughly. 

Covering  Capacity.  About  400  sq.  ft.  per  gallon  for  each  coat. 


Hydrolac  Asbestos  Putty 

A  compound  composed  of  pure  asphaltum,  waterproof  oils,  and  asbestos  fibre, 
of  consistency  slightly  softer  than  putty.  It  will  remain  flexible,  resist  temperature 
extremes,  and  conform  to  changes  due  to  expansion  and  contraction.  These  qualities 
make  this  material  valuable  for  roof  repair  work,  crack  filling,  pointing  up  chimneys 
and  general  repair  work.  It  also  is  used  as  a  plastic  roofing. 

Made  in  black  and  red. 

Directions.  Wire  brush  cracks  or  surfaces  to  be  treated.  Apply  with  plasterer’s  trowel 

or  thickness. 

Crescrete  Frostproofing 

Crescrete  Frostproofing  is  an  effective  anti-freeze  solution  to  be  mixed  with  the 
gauging  water,  for  placing  concrete  in  temperatures  below  freezing. 

The  use  of  Crescrete  lowers  the  freezing  point  of  the  water  and  thereby  makes 
winter  concrete  work  possible.  In  addition,  by  the  use  of  Crescrete,  a  denser,  firmer 
and  quicker  setting  concrete  will  be  secured. 

Directions:  Mix  Crescrete  with  the  gauging  water  in  proportions  as  shown  in 

the  following  table:
